The pain that you feel in your feet after a good deal of exercise is actually a sign of bad form. It mostly depends on how you land on your feet and how you keep your feet positioned throughout the workout. In order to find out the real cause, you need some good fitness advice, or better yet a good device.

The Sensoria Fitness Sock will do just that for you. This specially designed footwear tech will give you a bunch of data and insight on your workout techniques, and you will also be able to compare it with previous results to correct your form as you go. The kit comes with an anklet as well as a ‘smart sock’ both of which combine with the app to give you data on things like your cadence, foot landing and weight distribution, all essential if you’re to improve.

The product connects to your smartphone via the fitness apps available for both Android and iOS devices. The app connects to the phone via Bluetooth, and the data you learn could be enough to save you from future serious injury. The Sensoria Fitness Socks are available for pre-orders via Sensoria Fitness for $149.
